Function std::intrinsics::unchecked_shl

pub const unsafe extern "rust-intrinsic" fn unchecked_shl<T>(    x: T,     y: T) -> T where    T: Copy,

???? This is a nightly-only experimental API. (core_intrinsics)

intrinsics are unlikely to ever be stabilized, instead they should be used through stabilized interfaces in the rest of the standard library

Performs an unchecked left shift, resulting in undefined behavior when y < 0 or y >= N, where N is the width of T in bits.

Safe wrappers for this intrinsic are available on the integer primitives via the checked_shl method. For example, u32::checked_shl
